Regulator cooling device.

The regulator cooling device, will be used to place a voltage floor

restriction on a rail.

Properties:

- compatible:

	Usage: required

	Value type: <string>

	Definition: shall be "qcom,regulator-cooling-device"

- cdev-supply:

	Usage: required

	Value type: <phandle>

	Definition: phandle to the regulator to which the cooling device will

			place a floor mitigation.

- regulator-levels:

	Usage: required

	Value type: <U32 array>

	Definition: Array of regulator voltages the cooling device should

			use to place a floor restriction. The voltages should

			be specified in ascending order.

- #cooling-cells: Must be 2. Please refer to

			<devicetree/bindings/thermal/thermal.txt> for more

			details.

Example:

	mv_cdev: mx-cdev-lvl {

		compatible = "qcom,regulator-cooling-device";

		cdev-supply = <&regulator-cdev-supply>;

		regulator-levels = <RPMH_REGULATOR_LEVEL_OFF

			RPMH_REGULATOR_LEVEL_NOM>;

		#cooling-cells = <2>;

	};
